Furthermore, alterations in root morphology, quantity of root exudates and increases in rooting depth may be observed in an elevated [CO2] environment (Rogers et al. 1992; Nie et al. 2013).
The trap solution was lyophilized, and the dry matter was weighed and was considered to indicate the quantity of root exudates.
However, the nematodes in the cited study were obtained by extraction from large quantities of roots, and subsequently concentrated to rather high densities before inoculation.
Hence, erosion losses are minimized and large quantities of root and aboveground biomass are returned to the soil.
The quantity and quality of root exudates are a function of plant species, age of an individual plant, and external factors, such as biotic and abiotic stressors [34].
The distance between 2 elements xji and Rlk is the quantity of the root of, sum of, square of, deviation among xji and Rlk.
The sheer quantity and diversity of root beers dwarfs the quantity and diversity of any other soda, although the actual volume is but a trickle compared with the ocean of cola pumped out by the corporate giants that rule the global soda market.
In addition, herbicide-induced changes to the composition and/or the quantity of treated plant root exudates may further enhance the nutritional richness of the rhizosphere for microorganisms poised to metabolise these products.
Soil microbial communities are different between conifer and broad-leaved forests (Ushio et al. [2008]), which could release different quality and quantity of litter and root exudates (Sauheitl et al. [2010]).
The quantity of zinc in the roots decreased by 45%, whereas in the leaves, it went up by 23%.
